Description
Technical field
The present invention relates to moving communicating field, relate in particular to a kind of method for network access and system and a kind of relay station based on relaying.
Background technology
In order to adapt to the future broadband wireless communication systems High Data Rate, the basic demand of the high real-time and the end error rate, some new technology are introduced in the wireless communication system, and the wireless relay technology is exactly one of them.
The distance of the decay of radio signal power and its propagation is exponent function relation substantially.In the wireless communication system of honeycomb system, the decay of radio signal has directly determined the size of single honeycomb grid (coverage of a base station).And that the user that the characteristic of exponential damping has determined at center of housing estate can receive is very high, even is higher than the radio signal of standard, and on the contrary, the user of cell edge can only disclose faint signal, has influenced service quality.Simultaneously, even exponential damping causes in the very big transmitting power of center of housing estate increase, the improvement of cell edge signal quality is also very little.
In the wireless communication system in future, the user of cell edge also can require more intense signal, and existing sub-district system is difficult to meet the demands.If reduce the area coverage and the radius of single base station, then the cost of network laying can improve greatly.For to increase the covering of sub-district than the cost at the end, the service quality of Cell Edge User is provided, a kind of network architecture based on wireless relay becomes the basis of following radio communication.
As shown in Figure 1, the signal of base station (BS, Base Station) emission is exaggerated through relay station (RN, Relay Node), serves relay station user on every side.Signal can also amplify through a plurality of relay stations, reaches the place far away from the base station.The cost of relay station is much smaller than the base station, and therefore overall cost is less than simply dwindling the sub-district area.Owing to be wireless trunking scheme, the setting of relay station and change are more flexible in addition.Fig. 2 has shown the improvement of relaying to sub-district service quality, wherein, curve 1 is for only using the situation of base station, and curve 2 is the situation in conjunction with base station and relay station, as can be seen from Figure 2, if do not use relay station, along with the increase of base station distance, data throughout is on a declining curve always in the network, after having used relay station, signal power has obtained amplification near relay station, so effectively raise the data throughout of relay station near zone.
The method for network access that adopts relay station is arranged in the prior art, as shown in Figure 3, the method for network access of the motion " IEEE C802.16mmr-05/027r1 " in the 802.16mmr standards project that IEEE (IEEE, Institute of Electrical and Electronics Engineers) proposes is:
301, synchronized broadcasting content;
The relevant information of synchronising base station and relay station broadcasting up-downgoing channel.The content of base station and relay station broadcasting need be consistent.
302, initiate to insert request;
Terminal detects the information relevant with base station and up channel from broadcast, send to insert solicited message, for example application for registration, bandwidth request, request of data etc. on some up channel of appointment.
303, measure and report;
Relay station is measured the signal of the carrying access solicited message of terminal, and reporting base station.
304, access network.
The base station is selected by which relay station terminal to be served by the measurement result that reports.After selected, information such as the wide affirmation of base station hair band are given terminal and relay station, the network insertion success.
Fig. 4 is the signaling process figure of method for network access in " IEEE C802.16mmr-05/027r1 ", and Fig. 4 has embodied the flow direction of signaling.
But, as shown in Figure 3, the base station might not receive the access solicited message of terminal fully or disturbs and can't receive too greatly, if so relay station reporting measurement result then meaningless only, can not make the access network of the terminal success of the request of transmission, so terminal must be initiated to insert request again, thereby time that causes having increased on the whole accessing terminal to network;
Secondly, before accessing terminal to network, the measurement result of relay station must be waited in the base station, has the process that a wait relay station is measured so receive the access solicited message of terminal from the base station to accessing terminal to network, has increased the time of accessing terminal to network like this.
Summary of the invention
The technical problem to be solved in the present invention provides a kind of method for network access and system and a kind of relay station based on relaying, is used to accelerate the speed of accessing terminal to network.
Method for network access based on relaying provided by the invention comprises: terminal sends the access solicited message to base station and relay station; Relay station is transmitted described access solicited message to the base station; The base station is according to the accessing terminal to network of the access solicited message that receives at first with correspondence; The base station is chosen to be the relay station/base station of Terminal Service according to described measurement result; After being chosen to be the relay station/base station of Terminal Service, the base station switches to selected relay station/base station for the relay station/base station of Terminal Service with current.
Network access system based on relaying provided by the invention, comprise base station and relay station, terminal sends the access solicited message to base station and relay station, described relay station is directly transmitted the access solicited message that receives to described base station, measurement result is measured and generated to described relay station according to inserting solicited message, and described relay station is to base station reporting measurement result; Described base station is according to the accessing terminal to network of the access solicited message that receives at first with correspondence, and described base station is chosen to be the relay station/base station of Terminal Service according to described measurement result; After being chosen to be the relay station/base station of Terminal Service, the base station switches to selected relay station/base station for the relay station/base station of Terminal Service with current.
Above technical scheme as can be seen, the present invention has the following advantages:
At first, among the present invention, no matter whether the base station receives the access solicited message of terminal, relay station all can be transmitted to the base station after receiving the access solicited message that terminal sends, because obtaining the approach that inserts solicited message, the base station increases, probability also increases, so effectively avoided the repeating transmission of terminal, has improved the speed of accessing terminal to network;
Secondly, among the present invention, the opportunity that the user can select relay station to measure according to actual conditions, the invention provides two kinds of selectable situations, the one, relay station will insert solicited message again and send to the base station with measurement report after measurement is finished, another kind is to insert solicited message to separate situation about sending with measurement report, so improved application flexibility of the present invention;
At last, among the present invention, when after relaying stands in forwarding access request, measuring again, the base station is earlier according to receiving the accessing terminal to network of the request of access with correspondence, and then to being provided for terminal, the relay station/base station of service adjusts according to the measurement result that relay station sends subsequently, avoided access delay, so further accelerated the speed of accessing terminal to network because of waiting for that the relay station measurement causes.
